              friction, where the steady-state frictional resistance increases
              with sliding velocity over some range, is a generic feature of
              such interfaces. This physical behavior has very recently been
              linked to slow stick-slip motion. Here we elucidate the
              importance of velocity-strengthening friction by theoretically
              studying three variants of a realistic friction model, all
              featuring identical logarithmic velocity-weakening friction at
              small sliding velocities, but differ in their higher velocity
              behaviors. By quantifying energy partition (e.g. radiation and
              dissipation), the selection of interfacial rupture fronts and
              rupture arrest, we show that the presence or absence of
              strengthening significantly affects the global interfacial
              resistance and the energy release during frictional
              instabilities. Furthermore, we show that different forms of
              strengthening may result in events of similar magnitude, yet with
              dramatically different dissipation and radiation rates. This
              happens because the events are mediated by rupture fronts with
              vastly different propagation velocities, where stronger
              velocity-strengthening friction promotes slower rupture. These
              theoretical results may have significant implications on our
